JOSEPH J. CAUDLE, OF RICHMOND, VIRGINIA, ASSIGNOR TO BRITISH AMERICAN TOBACCO COMPANY LTD, OF NEW YORK, N. Y., A CORPORATION OF GREAT BRITAIN.

MACHINE FOR MAKING CIGARETTE-CONTAINERS.

Application filed January 21, 1918.

To all whom it may concern.

Be it known that I, J osnrrr J. CAUDLE, a citizen of the United States, residing at Richmond, county of Henrico, and State of Virginia, have invented a new and useful Improvement in Machines for Making Gigarette-Containers, of which the follow ing is a specification.

This invention relates to an improvei'nent in machines for making cigarette containers or paper cups in which cigarettes are packed for the market.

Machines for making such cigarette containers are provided with a succession of container forms over which the paper blanks are folded and pasted in the form of cups or packages open at one end. After the cigarettes are inserted in these cups, the open end thereof is closed and sealed. I-Ieretofore, it has been the custom to feed the blanks from the containers to the forms by hand. The present invention is a device for feeding such blanks to the forms automatically. -VVitl1 this and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then specifically pointed out in the claims hereunto appended.

In the accompanying drawings, which form a part of this specification and in which like characters of reference indicate the same or like parts,-Figure 1 is a side elevation of a device constructed in accordance with the invention; Fig, 2 is a sectional view upon an enlarged scale of a portion of the structure shown in Fig. 1; and Fig. 3 is an end elevation of the same structure.

In carrying the invention into eifect, there is provided a succession of traveling container forms, a source of container material supply, means for feeding the container material from said source to said forms, said means including a controlling member in the path of and actuated by said forms. In the best constructions, the source of container material supply consists in a magazine for supporting a stack of container blanks, and means are provided for feeding said blanks from the stack to said forms. The above mechanism may be varied in construction in many ways within the scope of the claims. The invention therefore is not to be restricted to the precise details of the structure shown and described.

Specification of Letters Patent.

Serial No. 212,922.

Referring to the drawings, 4 indicates a shaft which is one of the main shafts of a machine for making cigarette containers. This shaft carries a pulley 5 over which runs an endless belt 6. Secured at intervals to the belt 6 and caused to travel thereby is asuccession of container forms 7, each form being secured to the belt at its rear end only, as by means of rivets not shown. The particular construction of the machine for making cigarette containers of which the shaft 4, pulley 5 and belt 6 are a part, lies wholly outside of the present invention and further illustration and description of the same is therefore omitted in the interest of brevity and clearness.

Constructed to be mounted upon the main frame of the container making machine are two side frames 8 and 9. These side frames are connected by means of a bar 10 and a table 11. The table 11 serves to support a magazine 12 removably mounted between suitable gibs 13 fastened to the upper surface of the table 11. The magazine 12 is of a type well known in the art and its particular construction lies wholly outside of the present invention. A detailed description of thesame is therefore omitted in the interest of brevity and clearness. As clearly shown in Fig. 2, the magazine serves to confine a stack of container blanks, and it may be here remarked that each machine may be supplied with two magazines one of which may be loaded while the other is in position in the machine, so that a full magazine may be substituted for an empty one without undue loss of time.

Forming the bottom of the magazine 12 is a movable plate 14 secured to the upper part of a plunger 15 mounted to slide in a suitable bearing 16 formed in the table 11 before referred to. To the lower end of this plunger is connected one end of a cord 17 which passes over pulleys 18 and 19 mounted respectively in brackets 20 and 21 secured to the side frame 8 before referred to. The other end of the cord 17 carries a weight 22. By means of this weight and cord, the movable plate 14 constantly presses upward against the bottom of the stack of blanks and moves the stack upward as the blanks are removed from the top of the stack one by one.

Mounted adjacent the magazine is a pair of feed rollers 23-24. The feed roller 23 is preferably covered with rubber and is mounted upon a shaft 25 journaled in suitable fixed bearings in a bracket 26 rising from the table 11. Upon the outer end of the shaft 25 is fixed a small pulley 27. Over this pulley runs a belt 28 which also runs over a pulley 29 fast on the shaft 4: before referred to. By means of the mechanism just described, the roller 23 is given a continuous rotary movement. The roller 26L contacts with the roller 23 and is fast upon. a shaft 30 which is journaled in sultable boxes 31 slidably mounted in slots formed in the bracket 26 and in a bracket 32 rising from the table 11, opposite the bracket 26. The roller 24 is held down in contact with the roller 23 by means of rubber cushions 33 interposed between the j ournal boxes 3]. and cups 3a screwed to the brackets 26 and 32 over the journal box slots. Adjacent the feed rollers 23 and 24: is a curved chute 35, its upper section being concaved and inclined forwardly, while its lower section is substantially vertical and extends to a point near the periphery of the pulley 5 before referred to. The purpose of this chute is to guide blanks fed into it by means of the feed rollers 232l into position betweenthe belt 6 and an oncoming container form 7. The uppermost blank of the stack must be moved into position to be caught between the rollers 23 and 524. before the latter can act upon it. For this purpose there is provided a, dog 36 having a block rubber face 37 contacting with the uppermost blank of the stack. The dog 36 is pivoted at 38 to a carriage 39 slidably mounted upon a bar 40, one end of which is secured to the bracket 32 and the other end to a bracket d1 also rising from the table 11. One end of a link 4:2 is secured to the carriage 39 at 43, and its othe end is secured at 44 to the upper end of a lever 45, by means of which the carriage 39 and the dog 36 are caused to reciprocate along the open top of the magazine. The lever 45 is fulcrumed to a bar 46 cXtendin g across the machine between the side frames 8 and 9. Its lower end carries acam how] 47 engaging a cam wheel having a pluarlity of cam surfaces 48. This cam wheel is fast upon a shaft 49 extending across the machine and journaled in b-sarings 50 and 51. respectively secured to the side frames 8 and 9. The cam bowl 417 is held in contact with the cam surfaces 48 through the agency of a spring 52, one end of which is fast to a pin 53 carried by the lever and the other end to a pin 54: secured in theside frame 9.

The cam wheel having a plurality of cam surfaces 48 forms a part of a controlling member for operating the lever 45. Another part of this controlling member is formed by a block 55 secured to the shaft 49 and provided with four radial arms 56,

these arms being in the path of and adapted to be actuated by the container forms 7 as they pass over the pulley 5.

As a container form 7 comes into contact with one of theradial arms 56 of the controlling member, it rotates the shaft 49 and the cam wheel a quarter revolution. The lever 45 is thus operated to cause the dog 36 to push the uppermost blank in the stack forward into the bight of the feed rollers 2324. These feed rollers are operating at a surface speed much higher than that of the dog 36 during its forward movement; the rollers therefore as soon as they seize the blank cooperate to increase its velocity and push it into the upper part of the chute 35, as indicated by the arrow in Fig. 1. As soon as the blank passes the feed rollers 2324:, its rear end falls into the chute and the blank is then switched back or permitted to slide down through the chute into posi tion between the belt 6 and the particular container form which has j ust operated and passed the controlling member. The blanks caught between the belt 6 and container form 7 are thereby forwarded to the proper mechanism for folding them about the forms. a
